Possibilities of Using Sources of Neutron Radiation for Radiation Testing of Dikes of Trunk Pipelines

Methodical aspects of in-tube testing of the media surrounding a trunk pipeline are considered. The method is based on radiating media with a source of fast neutrons and the subsequent measurement of the albedo of thermal neutrons and neutron-capture gamma rays. On the basis of a laboratory model of a pipeline segment, a set of model experiments was conducted to assess the information content of radiation signals for different types of media surrounding pipes.
